I asked to remove the words "Devicetree bindings" and this was not finished.

Now you mention that entire name of device is wrong... It's confusing. I don't know what device you are describing here. I expect you know. :)

What is this binding about exactly?
[Jerry Huang] 
I double checked the SPI device used on MikcroBus, which is not sx1301.
Now we have two MikcroBus click boards, BEE click and BLE P click, both of them have the SPI interface through MikcroBus.
So I can't use the previous name "semtech, sx1301".
